We'd really love to get Construct 2 on Steam, to help broaden our reach to a wider audience. Steam Greenlight just started accepting software submissions, so we've submitted Construct 2. We need as many people as possible to upvote it - so please head over and click the big 'Yes' button! :)
If you don't have a Steam account, it's free to sign one up. It would be great if you could get a few friends to vote as well! Thanks to everyone who helps us!
